.SH DESCRIPTION
.sp
.LP
The \fBmore\fR utility is a filter that displays the contents of a text file on
the terminal, one screenful at a time.  It normally pauses after each
screenful. \fB/usr/bin/more\fR then prints \fB--More--\fR and
\fB/usr/xpg4/bin/more\fR then prints \fIfile\fR at the bottom of the screen. If
\fBmore\fR is reading from a file rather than a pipe, the percentage of
characters displayed so far is also shown.
.sp
.LP
The \fBmore\fR utility scrolls up to display one more line in response to a
\fBRETURN\fR character. \fBmore\fR displays another screenful in response to a
\fBSPACE\fR character. Other commands are listed below.
.sp
.LP
The \fBpage\fR utility clears the screen before displaying the next screenful
of text. \fBpage\fR only provides a one-line overlap between screens.
.sp
.LP
The \fBmore\fR utility sets the terminal to \fBNOECHO\fR mode, so that the
output can be continuous. Commands that you type do not normally show up on
your terminal, except for the \fB/\fR and \fB!\fR commands.
.sp
.LP
The \fB/usr/bin/more\fR utility exits after displaying the last specified file.
\fB/usr/xpg4/bin/more\fR prompts for a command at the last line of the last
specified file.
.sp
.LP
If the standard output is not a terminal, \fBmore\fR acts just like
\fBcat\fR(1), except that a header is printed before each file in a series.
.SH OPTIONS
.sp
.LP
The following options are supported for both \fB/usr/bin/more\fR and
\fB/usr/xpg4/bin/more\fR:
.sp
.ne 2
.na
\fB\fB-c\fR \fR
.ad
.RS 7n
Clears before displaying. Redraws the screen instead of scrolling for faster
displays. This option is ignored if the terminal does not have the ability to
clear to the end of a line.
.RE

.sp
.ne 2
.na
\fB\fB-d\fR \fR
.ad
.RS 7n
Displays error messages rather than ringing the terminal bell if an
unrecognized command is used. This is helpful for inexperienced users.
.RE

.sp
.ne 2
.na
\fB\fB-s\fR \fR
.ad
.RS 7n
Squeeze.  Replaces multiple blank lines with a single blank line. This is
helpful when viewing \fBnroff\fR(1) output on the screen.
.RE

.SS "/usr/bin/more"
.sp
.LP
The following options are supported for \fB/usr/bin/more\fR only:
.sp
.ne 2
.na
\fB\fB-f\fR \fR
.ad
.RS 15n
Does not fold long lines. This is useful when lines contain nonprinting
characters or escape sequences, such as those generated when \fBnroff\fR(1)
output is piped through \fBul\fR(1).
.RE

.sp
.ne 2
.na
\fB\fB-l\fR \fR
.ad
.RS 15n
Does not treat \fBFORMFEED\fR characters (Control-l) as page breaks. If
\fB-l\fR is not used, \fBmore\fR pauses to accept commands after any line
containing a \fB^L\fR character (Control-l). Also, if a file begins with a
\fBFORMFEED\fR, the screen is cleared before the file is printed.
.RE

.sp
.ne 2
.na
\fB\fB-r\fR \fR
.ad
.RS 15n
Normally, \fBmore\fR ignores control characters that it does not interpret in
some way. The \fB-r\fR option causes these to be displayed as \fB^\fR\fIC\fR
where \fIC\fR stands for any such control character.
.RE

.sp
.ne 2
.na
\fB\fB-u\fR \fR
.ad
.RS 15n
Suppresses generation of underlining escape sequences. Normally, \fBmore\fR
handles underlining, such as that produced by \fBnroff\fR(1), in a manner
appropriate to the terminal. If the terminal can perform underlining or has a
stand-out mode, \fBmore\fR supplies appropriate escape sequences as called for
in the text file.
.RE

.sp
.ne 2
.na
\fB\fB-w\fR \fR
.ad
.RS 15n
Normally, \fBmore\fR exits when it comes to the end of its input. With
\fB-w\fR, however, \fBmore\fR prompts and waits for any key to be struck before
exiting.
.RE

.sp
.ne 2
.na
\fB\fB-\fR\fIlines\fR\fR
.ad
.RS 15n
Displays the indicated number of \fIlines\fR in each screenful, rather than the
default (the number of lines in the terminal screen less two).
.RE

.sp
.ne 2
.na
\fB\fB+\fR\fIlinenumber\fR\fR
.ad
.RS 15n
Start up at \fIlinenumber\fR.
.RE

.sp
.ne 2
.na
\fB\fB+/\fR\fIpattern\fR\fR
.ad
.RS 15n
Start up two lines above the line containing the regular expression
\fIpattern\fR. \fBNote:\fR Unlike editors, this construct should \fInot\fR end
with a `\fB/\fR.' If it does, then the trailing slash is taken as a character
in the search pattern.
.RE

.SS "/usr/xpg4/bin/more"
.sp
.LP
The following options are supported for \fB/usr/xpg4/bin/more\fR only:
.sp
.ne 2
.na
\fB\fB-e\fR \fR
.ad
.RS 17n
Exits immediately after writing the last line of the last file in the argument
list.
.RE

.sp
.ne 2
.na
\fB\fB-i\fR \fR
.ad
.RS 17n
Performs pattern matching in searches without regard to case.
.RE

.sp
.ne 2
.na
\fB\fB-n\fR \fInumber\fR \fR
.ad
.RS 17n
Specifies the number of lines per screenful. The \fInumber\fR argument is a
positive decimal integer. The \fB-n\fR option overrides any values obtained
from the environment.
.RE

.sp
.ne 2
.na
\fB\fB-p\fR \fIcommand\fR \fR
.ad
.br
.na
\fB\fB+\fR\fIcommand\fR \fR
.ad
.RS 17n
For each file examined, initially executes the \fBmore\fR command in the
\fIcommand\fR argument. If the command is a positioning command, such as a line
number or a regular expression search, set the current position to represent
the final results of the command, without writing any intermediate lines of the
file. For example, the two commands:
.sp
.in +2
.nf
\fBmore -p 1000j file
more -p 1000G file\fR
.fi
.in -2
.sp

are equivalent and start the display with the current position at line 1000,
bypassing the lines that \fBj\fR would write and scroll off the screen if it
had been issued during the file examination. If the positioning command is
unsuccessful, the first line in the file will be the current position.
.RE

.sp
.ne 2
.na
\fB\fB-t\fR \fItagstring\fR \fR
.ad
.RS 17n
Writes the screenful of the file containing the tag named by the
\fItagstring\fR argument. See the \fBctags\fR(1) utility.
.RE

.sp
.ne 2
.na
\fB\fB-u\fR\fR
.ad
.RS 17n
Treats a backspace character as a printable control character, displayed as a
^H (Control-h), suppressing backspacing and the special handling that produces
underlined or standout-mode text on some terminal types.  Also, does not ignore
a carriage-return character at the end of a line.
.RE

.sp
.LP
If both the \fB-t\fR\fI tagstring\fR and \fB-p\fR\fI command\fR (or the
obsolescent \fI+command\fR) options are given, the \fB-t\fR\fI tagstring\fR is
processed first.
.SH USAGE
.SS "Environment"
.sp
.LP
\fBmore\fR uses the terminal's \fBterminfo\fR(5) entry to determine its display
characteristics.
.sp
.LP
\fBmore\fR looks in the environment variable \fBMORE\fR for any preset options.
For instance, to page through files using the \fB-c\fR mode by default, set the
value of this variable to \fB-c\fR. (Normally, the command sequence to set up
this environment variable is placed in the \fB\&.login\fR or \fB\&.profile\fR
file).
.SS "Commands"
.sp
.LP
The commands take effect immediately. It is not necessary to type a carriage
return unless the command requires a \fIfile\fR, \fIcommand\fR,
\fItagstring\fR, or \fIpattern\fR. Up to the time when the command character
itself is given, the user may type the line kill character to cancel the
numerical argument being formed. In addition, the user may type the erase
character to redisplay the `\fB--More--(\fR\fIxx\fR%)' or \fIfile\fR message.
.sp
.LP
In the following commands, \fIi\fR is a numerical argument (\fB1\fR by
default).
.sp
.ne 2
.na
\fB\fIi\fRSPACE \fR
.ad
.RS 13n

the first column cancels the search command.
